Forums Scripts & Popups Advertisement Dialog

I'm creating a dialog for easy advertisement set up for the IRC network for a game I play. It'll have an option to input the text you want to advertise (with bold and underline able to be used), as well as a check box of all the channels meant to advertise in on the network (only three right now).

So far, I have this:


Now, that is pretty much exactly what I want, except for a few added things I will put in later. Such as more space to see a preview of the advertisement they put in, as well as a preview button, and maybe some other added text for other things. Anyhow..

What I'm wondering is how do I make it so if people upload the script, all they have to type it /swcad-su instead of /dialog -m SWC-AD SWC-AD to open the dialog?

Also, where can I find a good tutorial on how to add commands to all those things?

create a alias for it?

Or more simple :

Well, this'll be the first thing I've ever coded. I'm still learning.

What is different about this code and sparta's code?

I'm playing with dialog's as well that's why i ask.

my code is a bit longer then the code he wrote, thats about it

;------- Edit

I guess my code are a bit "old", and the other example here have the "new" style.

Mmm only your code works except for that already running message, that doesn't seem to work.
Wims code doesn't do anything at all.

I've tested my code and it works perfectly, if the dialog isn't open, then open it,else just make it the active window (and sparta's code should works too)
